Found at Mayville Ledge Beech-Maple Woods SNA in east-central Wisconsin in northern USA on 31.VII.2021. Found projecting 3-4mm out of trunk of debarked fallen hardwood tree in mixed hardwood forest. Looked relatively fresh, so presumably the adult had emerged not too long before I found the exuvium. Initially I presumed it was dipteran. Coleoptera was suggested on Bugguide. Confirmation/correction appreciated. Bigger pics here. jgruber111 attached the following image:  [190.82Kb] Edited by jgruber111 on 03-08-2023 15:22 |

Looks more like Limoniidae to me |

Just wanted to give an update on this. I got confirmation from Even Dankowicz that this is genus Symmerus in Ditomyiidae. I recently got pics of an adult eclosing from such an exuvium - https://www.flick...078261696/. There are also similar images out on iNat - https://www.inatu...id=1011029 Edited by jgruber111 on 03-08-2023 15:28 |
